hi i'm trying send data textview activity in destination activity doesn't pick intent data id. clarify, in destination activity not recognize variable "username" . how fix this? mainactivity activity (sender) public final static string username = "com.example.eugen.test.mainactivity.etusername"; intent destination_intent = new intent(this, destination.class); destination_intent.putextra(username,etusername.gettext()); startactivity(destination_intent); destination activity string usernamereceived = null; usernamereceived = getintent().getstringextra(destination.username); just change destination.username mainactivity.username variable username declared static in mainactivity . , ivan v suggested, practice create constants file , declare static constants there, make things more cleaner.

i use following command before sending js files server: node --check <filename>.js that way can sure there no gross errors before forwarding file server (i.e. missing ')' generates error). what noticed, though, node.js not give me error if not put semicolon @ end of line. happen, looking @ command line options, cannot see such feature. is there way node.js ? what noticed, though, node.js not give me error if not put semicolon @ end of line. that's because javascript has error-correction mechanism called automatic semicolon insertion (see this question's answers more asi), parser insert semicolons token stream if they're missing in many cases. node isn't going give information. i recommend using proper lint tool instead, such eslint , jshint , or of several others.

usually install files in folder seems it's extacting in node_modules ? did mess up? i looked on internet couldn't find anwser. that's how npm dependency resolution works since version 3, efficiency purposes. more information have @ docs. https://docs.npmjs.com/how-npm-works/npm3

i working on qt 5.5 / 4.8 now. worry whether timeout() signal (occasionally）sent after timer explicitly stopped calling stop() on instance? i hope timeout() signal sent between start() , stop() , truth? my situation is: start() , stop() both called in main thread, , timeout() signal connect directly connection. (i know queued connection cannot guarantee above statement.) quick answer: no , won't called on of cases, there @ least 1 exception. a situation when may called if have used queued connections . here may associated slots called after you've stopped if, example, qtimer::timeout signal happens emitted before stopping timer. in case above slots queued (but not called), may happen call qtimer::stop before slots invoked. if use queued connections can check qtimer::isactive() @ beginning of slot (you'll need way access timer of course, maybe member of class).
